483 polychromatic glass panels adorn the kindergarten in Tinashui, China, and bring smiles to young faces. Various round glass panels in colors of the rainbow perfectly open already a spacious building in forms of windows, railings, and doorways. The fairytale-like building designed by architect Keiichiro Sako looks like a giant marshmallow with white exterior and interior and only colorful glass that breaks the rhythm but fitts so flawlessly. Sako wrote: “Color shades can grow and shrink as colors overlap and become different colors, or move from a vertical plane to a horizontal plane and back again. I hope that spending childhood in this beautiful light will foster the creativity of the children.” On the open atrium (center of the building above which is the glass roof) sunlight comes from all the sides as children enjoy the kaleidoscopic effect. Children can also enjoy a beautiful translucent view of the city that surrounds their light castle. What a kindergarten this is!
